find the lowest common multiple of a number js code example

Example: find least common multiple javascript

function smallestCommons(arr) {
  var max = Math.max(...arr);
  var min = Math.min(...arr);
  var candidate = max;

  var smallestCommon = function(low, high) {
    // inner function to use 'high' variable
    function scm(l, h) {
      if (h % l === 0) {
        return h;
      } else {
        return scm(l, h + high);
      }
    }
    return scm(low, high);
  };

  for (var i = min; i <= max; i += 1) {
    candidate = smallestCommon(i, candidate);
  }

  return candidate;
}

smallestCommons([5, 1]); // should return 60
smallestCommons([1, 13]); // should return 360360
smallestCommons([23, 18]); //should return 6056820
